Application led October 30, 1905. Serial No. 285,198.

T0 all whom t may concern,.-

Be it known that I, JOSEPH DAIN, a citizen of the United States, residing at Ottumwa, county ofWapello, State of Iowa, have invented certain new and useful Improvements in Hay-Stackers, of which the following is a full and com lete specification, reference being had to the accompanying drawings.

This invention relates to hay-stackers of that class wherein the hay to be elevated is placed upon .a carrier that is pivotally connected to a supporting-frame, such pivoted carrier being adapted to be elevated with its load by being turned Yon its pivots through the medium of power applied through -elevating-ropes- One of the Objects of my invention is to provide means for automatically causing the pivoted carrier to at once turn on its pivots after it has reached the limit of its upward movement and discharged its load, so that there will be no delay in causing such carrier to resume itslowermost position ready to receive anotherlload.

Another object of 'my' invention is to provide an improved bracing construction for the inner or rear end of said ivoted carrier, whereby it will be made muc stronger than such carriers have heretofore been made, such bracing construction being of a character to prevent any interference with the supporting-frame. f

It is further the object of my invention to improve the construction of machines of this character in various details.

I accomplish the objects of my invention by the means shown in the drawings and hereinafter specifically described.

That which I believe to be new will be pointed out in the claims.

In the drawings, Figure 1 is a side elevation showing the parts in position to receive a'load. Fig. 2 is a plan view. Fig. 3 is a side elevation showing the pivoted carrier in its elevated position. Fig. 4 is an enlarged detail, being a plan view of one of the two sets of spring devices that are employed to avoid shock to the pivoted carrier as it completes its upward movement and that aid in returning such carrier to, its load-receiving position.

Referring to the several l.figures of the drawings, 10 10 indicate the side bars of the supporting-frame, these .side bars being connected near their rear ends by a sill 11 and near their forward ends by an axle 12, the

ends of such axle lbeing preferably secured in brackets 13. Intermediate ofthe end sill 11 and the axle 12 the side bars 10 are in the construction shown further secured together by cross-pieces 14 and 15. f

16 indicates short posts laced opposite each other and secured to the side bars 10. Extending rearwardly from each of these posts 16 and toward the central portion of Athe inner or rear` sill 11 are brace-bars 17.

The rear ends of these brace-bars 17 are secured in the construction shown to brackets 18.

19 indicates another and shorter brace extending from each post 16 downward and secured at its lower endto one of the side bars 10 just in rear ofthe axle 12.

20 indicates the side bars of the pivoted carrier-frame, which carry at their outer or forward ends a series of teeth 21, upon which the hay to be elevated is deposited and which is held on such teeth by an adjustable set of teeth 22, such latter teeth being adjustedto the desired angle by means ofthe adjusting-bars 23, as usual. There are shown two lifting-frames, one consisting of a pair of bars 24pivoted to the posts 16, and the other consisting'of a pair of bars 25, in the construction shown pivoted on the axle 12 close to the wheels on such axle. Each of these lifting-frames, as ordinarily constructed and as here illustrated, has its two bars inclined toward each other at the upper ends, and the upper ends of the two lifting-frames 24 and 25 are joined together by a rigid connection 26, pivotally secured to the bars of each lifting-frame. The lifting-frame composed of bars 24 is connected with the pivoted carrier by suitable devices, such as that shown and indicated by 24a or by any other suitable IOO that unites the upper `ends of the bars 25 and passes down and over a pulley 29, that is secured to the end sill 11, and thence up and over a second pulley 30, carried at the upper ends of the elevatingvframe 25, and thence down and around a pulley 31, that is also atlio tached to said sill 11. Thisconstruction and arrangement of lifting-frames, rope, and pulleys are old and well understood, and it will be recognized that when power is applied to the end of the rope the lifting-frames 24 and 25 will turn on their supporting-pivots, and the pivoted carrier-frame will be raised into the position shown in Fig. 3, and the load of hay carried thereby on the teeth will be discharged.

It has been common to provide a rope attached to the carrier-frame to limit the extent to which such carrier-frame can be turned on its pivots and to prevent its being turned farther than is necessaryior desired, which rope has been fastened at a suitable point on the supporting-frame. I provide such ropes,which in the drawings are indi cated by 32, two of such ropes being shown,

onefor each side of the machine, and each rope 32 being secured to the pivoted carrier by a metal loop or eye 33. Instead of securing the opposite ends of such ropes 32 to the supporting-frame, as has heretofore been the practice, I attach each rope to a hook 34, that is formed on the end of a rod that is bent into the shape of an eye or ring 35 and that encircles the axle 12 near the forward or outer end of the machine. 36 indicates two coiled springs around the said axle 12, and against the inner end of each of which one of the rings or eyes 35 is adapted to bear, the other end of the coiled spring being held against the inner face of the bracket 37, secured to the said axle 12, said bracket also having projecting arms between which is provided a small guideeroller 3S, under which one of the ropes 32 runs. By this arrangement of a roller 38 near each end of the axle and by passingone of the ropes 32 under it a straight direct pull will be had on the eye 35, causing a proper compression of the lslpiing 36 when such pull on the rope 32 is 39 indicates a pair of small wheels journaled on the axle 12 between the side bars 10 and the brackets 37. At the opposite end of the machine are shown small runners 40, the vertical Shanks of which are loosely journaled in brackets 41, so as to permit the runners to turn freely as required.

When the pivoted carrier is in its raised po sition and carrying a load of hay, there is of course a great strain on the ypivoted carrier, and owing to the length of the side bars of such carrier unless the load is evenly distributed there is at times danger of distorting the parts so as to interfere with their free and easy operation, and great strain is brought to bear upon the pivots of this carrier. It is necssary that the side bars of this pivotedcarrier lie outside of the elevated brace-bars that run from the post 16 backward, and by reason of that factk and by reason of the fact that it has heretofore seemed necessary to run such elevated brace-bars back in substantially the same horizontal plane as the side bars of the supporitng-frame it has not been possible to give adequate bracing support to the side bars of the pivoted carrier. By my construction, however, I arrange these elevated brace-bars that run from the posts 16 in a diagonal direction toward the central portion of the rear sill, and room is thereby provided for ample bracing of the side bars of the pivoted carrier. Such bracing is indicated in the drawings by two bars 42 42, each of which is secured at its forward end in the construction shown to the inner face of one of the side bars 20 of the carrierframe, and extending back in a diagonal direction practically parallel to the diagonal direction of the adjacent raised brace 17 has its rear end pivotally connected with the end sill 11, such pivotal connection in the construction shown being to the bracket 18, to which one of the raised brace-bars 17 is attached. Each diagonal brace 42 is further secured to one of the side bars 20 of the carrier-frame by a short cross-piece 43. By this construction and arrangement of parts it is evident that the supporting-frame can be made just as rigid with its rearwardly-ex tending raised brace-bars 17 extending in a. diagonal direction toward the center of the end sill as if they came straight back and were secured near the ends of such end sill, as has formerly been the case, while it is clear that by so arranging these raised bracebars the carrier-frame can be made much stronger and stiffer by reason of the bracing that can be given it by the bars 42, as shown, than under the old constructions.

By having the ropes 32 of a proper length pressure will be brought to bear upon the inner ends of the coiled springs 36, so as to compress such springs just as the carrierk frame has about completed its swinging movement to discharge its load, and thereby a cushioning effect will be had, tending to relieve the carrier-frame of shock and jar as it comes to a stop', and as the load is discharged the reaction or expansion of the springs will, through the ropes 32, give a su'l'licient pull on the raised carrier to cause it to turn back on its pivots to again settle into position to receive another load.

The axle 12 serves not only as an axle proper for the wheels 39, but serves also as a suitable device to which the bars 25, composing one of the lifting-frames, are pivoted, and in .addition to these functions it affords an eflicient brace between the forward ends of the side bars of the supporting-frame and also serves to properly carry the two springs 36.
